2. Slack
Slack is a workplace messaging app designed primarily for team communication and collaboration. It organizes conversations into channels, allowing users to keep discussions structured.
While it offers integrations with various third-party tools such as project management and file-sharing apps, its reliance on multiple notifications and threads can sometimes feel overwhelming.
The Slack messaging app includes basic messaging features, voice and video calls, and file sharing, but some advanced functionalities require paid plans.
Slack Key Features
- Channel-Based Messaging: Organizes conversations into topic-specific channels.
- Integrations: Connects with various business tools like Google Drive and Trello.
- Searchable Message History: Allows users to find past conversations (limited in the free version).
- Basic Voice & Video Calls: Supports one-on-one calls for free; group calls require a paid plan.

3. WhatsApp
WhatsApp is a widely used messaging app that offers text, voice, and video communication. While it is convenient and free, it has several limitations.
Privacy concerns have grown due to its data-sharing policies with its parent company, raising questions about user security. The app relies on a phone number for registration, limiting anonymity and flexibility.
While it supports end-to-end encryption, backups stored on cloud services may not be fully secure.
Additionally, WhatsApp lacks advanced business integrations and productivity tools, making it less suitable for workplace collaboration compared to other messaging apps.
WhatsApp Key Features
- End-to-End Encryption: Chats are encrypted, but cloud backups are not fully protected.
- Phone Number Requirement: Users must link their account to a phone number, reducing anonymity.
- Limited Multi-Device Support: While available, it still has syncing issues across devices.
- Basic File Sharing: Allows media sharing but with strict file size limits.
- Lack of Business Features: Minimal integrations with productivity tools, making it less effective for professional use.
4. Telegram
Telegram is a cloud-based messaging app known for its speed and large group chat capabilities.
However, despite its reputation for security, its default chats are not end-to-end encrypted, meaning messages can potentially be accessed by third parties.
Users must manually enable secret chats for encryption, which limits usability across multiple devices. The app also allows large groups and channels, but this makes it prone to spam, scams, and misinformation.
Additionally, its file-sharing features, while extensive, can be exploited for piracy and unauthorized content distribution. Unlike other messaging apps, Telegram lacks strong business integrations, making it less practical for professional use.
Telegram Key Features
- Cloud-Based Storage: Messages sync across devices but lack default end-to-end encryption.
- Secret Chats: Offers encryption, but only for single-device conversations.
- Large Group & Channel Support: Can host thousands of members but is vulnerable to spam and fake accounts.
- File Sharing: Allows large file uploads, but this can lead to misuse and content piracy.
- Limited Business Features: Lacks native tools for workplace communication and integrations.
5. Microsoft Teams
Microsoft Teams is a collaboration platform and messaging app designed for workplace communication and team coordination, but it comes with several drawbacks.
One major issue is its cluttered interface, which can be overwhelming for new users. The app is often criticized for being resource-heavy, leading to slow performance on some devices.
While it offers a variety of features, many users find it difficult to navigate, especially for basic tasks like searching for messages or managing notifications.
Additionally, file-sharing and collaboration can sometimes be glitchy, and integration with other non-Microsoft tools is limited and often requires additional configuration.
Teams also lacks customization options for individual users, which can be frustrating for those who prefer more control over their experience.
Teams Key Features
- Team Channels & Chats: Useful for organizing conversations, but can get cluttered quickly.
- Integration with Microsoft 365: Works well with Microsoft tools but has limited support for third-party apps.
- Video & Voice Calls: Good for meetings, but lacks some advanced features found in dedicated video platforms.
- File Sharing & Collaboration: Functional, but prone to occasional glitches or slowdowns.
- Limited Customization: Minimal options for personalizing the user interface or settings.

6. Signal
Signal is a messaging app known for its focus on privacy and security, but it has several limitations. While it offers end-to-end encryption by default, it can be difficult for non-technical users to understand its setup and functionality.
The app is also limited in features compared to other messaging platforms; it lacks robust group management tools, making it less suitable for larger teams or organizations.
Additionally, Signal’s file-sharing capabilities are limited, with size restrictions and no cloud storage options. Users also face occasional performance issues, such as slow message delivery and syncing problems across devices.
Furthermore, Signal’s reliance on a phone number for registration limits its usability for those seeking more privacy or anonymous communication.
Signal Key Features
- End-to-End Encryption: E2E offers strong privacy but may be difficult for some users to set up.
- Limited Group Management: Lacks advanced tools for managing larger groups or teams.
- Restricted File Sharing: File size limits and no cloud storage for media.
- Performance Issues: Occasional delays in message delivery and syncing.
- Phone Number Requirement: Requires a phone number for registration, limiting anonymity.
